Running a 'Surveillance Detection Route' (SDR) as a Civilian

What Spies Use to Detect Tails, Simplified.

Using SDRs gives ordinary people a simple but powerful way to spot stalkers, adversaries, and unwanted followers without confrontation.

A strategically planned path that turns an ordinary walk or drive into a series of quiet tactics. Each designed to reveal whether that nagging shadow behind you is coincidence, curiosity, or true surveillance.

Civilians don’t need to live like covert operatives to borrow a few of our tools. A Surveillance Detection Route - SDR for short, is a pre-planned sequence of movements that lets you test whether someone’s following you.

It’s not for heroics or outmaneuvering someone in a movie-style chase. An SDR is about controlled awareness and observations in a structured way so you can separate paranoia from genuine threat. Each move giving you a chance to confirm or dismiss suspicion without escalating the situation. An SDR replaces guesswork with confidence, turning unease into actionable decisions.

This guide adapts professional tradecraft to everyday life - commutes, school runs, travel days, jogging routes, shopping - so anyone can run SDRs anywhere.

An SDR turns the city into a mirror that shows you what’s really behind you.

What an SDR Is

Definition: An SDR is a route made of short, purposeful “legs.” Each leg is designed to create a clear observation point: if a particular person or vehicle appears across several legs where they shouldn’t naturally reappear, you’ve likely got surveillance or a stalker.

Think of an SDR like stress-testing your daily path. Instead of just walking or driving straight to your destination, you add a few deliberate turns, pauses, or stops along the way. If the same person or vehicle keeps showing up after each of those changes, it’s a strong clue they’re intentionally following you. If not, you’ve only taken a slightly longer route, but you’ve gained peace of mind.

What it’s for:

• Confirm or dismiss that nagging feeling you’re being followed.

• Break your routine safely when you suspect you were targeted on a habitual route.

• Create opportunities to move to a safer location with witnesses, lighting, and cameras.

• Collect clean observations to share with police, building security, or a trusted contact.

What it’s not:

• It’s not a game of shaking law-enforcement unless your position or work overrides local entities.

• As a civilian, it’s not for confrontation. Your goal is information, safety, and documentation.

  In the streets, awareness is your strongest weapon and the easiest one to neglect.

Ground Rules Before You Start

1. Stay legal, and calm. Every leg must be lawful, non-aggressive, and defensible. No trespassing, no sudden dangerous maneuvers, no baiting.

2. Favor safety over cleverness. Build your route around safe havens - places with people, lighting, and cameras (cafés, big pharmacies, hotel lobbies, transit stations, police stations).

3. Use the Rule of Three. One coincidence means nothing. Two is interesting. Three independent indicators across separate legs is enough to act.

4. Don’t lead a follower to private locations. If you’re worried, don’t go home, to a child’s school, or to a friend’s residence. Finish at a safe public place.

5. Phone discipline. Battery up, share live location with a trusted person, and have a pre-agreed code phrase that means “call me now” or “call authorities.”

6. Document, don’t dramatize. Discreet notes, time stamps, and simple descriptions beat shaky video. If filming helps you feel safer, keep it legal and non-provocative.

The beauty of an SDR is that it turns suspicion into certainty without ever breaking stride.

Principles of a Good SDR

• Baseline First. Know what “normal” looks like where you are: common foot traffic, usual parking spots, typical pace. Deviations pop when you know the baseline.

• Blend Into Normal Movement. Every leg should look like something a regular person might naturally do. Ducking into a café, checking a bus schedule, or taking a short loop - so you don’t draw attention to yourself.

• Legs With Purpose. Each leg creates a test: a direction change, a brief stop, a short loop, an indoor/outdoor transition, or a visibility shift.

• Plan for Stress. Build routes that are simple enough to remember even when your adrenaline is up; complexity breaks down fast under pressure.

• Clarity Over Complexity. Fewer, cleaner legs beat a maze. Aim for 20-30 minutes with 4-6 legs you can remember under stress.

• Safe-Haven Anchors. Start and end at places where you can ask for help. Ideally, every second leg passes another safe haven.

• One Change at a Time. Each leg should change a single variable (direction, pace, environment) so your observations mean something.

• Exit Strategy Built-In. Always know where and how your SDR ends, whether that’s a staffed safe haven, a well-lit public space, or a direct call to authorities.

An operative trusts instinct, but always tests it against reality.

Indicators of Possible Surveillance

• Repetition: The same person or vehicle shows up in three distinct places where normal movement wouldn’t explain it.

• Mirroring: They match your pace, pauses, or direction changes without a natural reason.

• Positioning: They choose locations with line-of-sight on you - opposite corners, parked facing your vehicle, or repeatedly taking spots that give them visual advantage.

• Repeated Presence Across Environments: The same individual reappears in very different settings (on the street, then inside a shop, then back outside) without explanation.

• Behavioral Tells: Loitering without purpose, pretending to be busy on a phone, or exaggeratedly noticing surroundings only when you move.

• Grouping and Separation: People who appear together, split to cover different angles, then regroup later.

• Over-Covering: A follower who switches street sides, lanes, or seating positions just to maintain their view of you.

• Pace Inconsistency: Alternating between speeding up and slowing down unnaturally in order to stay close.

Good tradecraft makes the predictable unpredictable.

Build Your Own SDR: Step-by-Step

An SDR isn’t complicated and not about taking the longest or most confusing path. It’s stringing together a handful of short, ordinary movements that create opportunities to observe. The goal is to build a sequence that quietly tests whether someone stays with you across changes in direction, pace, or environment. With just a few legs and some forethought, anyone can put a simple SDR into practice almost anywhere.

Step 1) Pick Your Start, Finish, and Backup

• Start: Anywhere you can quietly plan - office lobby, gym entrance, grocery store. Do a quick baseline scan.

• Finish: A staffed, well-lit location you can remain in (café with big windows, hotel lobby, police station, 24-hour pharmacy).

• Backup: A second finish nearby, in case the first is closed or crowded.

Step 2) Choose 4–6 Legs (20–30 Minutes Total)

Below is a civilian-safe template. You can run it on foot or while driving, but keep it calm and lawful either way.

[Leg A]

Baselining Walk/Drive (5 minutes)

Purpose: Establish what’s normal and let any casual overlap peel off.

Do: Move at a natural pace along a moderately busy street. Note faces, clothing colors, vehicle types, and any distinctive features.

Watch for: Someone who appears to focus on you early, or a vehicle that seems to hang back without passing despite gaps.

[Leg B ]

Direction-Change Test (2–3 minutes)

Purpose: Create a low-probability repeat.

Do: Make a turn you don’t normally make - e.g., cut across to a parallel street or take the next side street and rejoin later. If driving, take an extra right or left that still keeps you legal and safe.

Watch for: The same person/vehicle making the same unnecessary change. Note time and place.

[Leg C]

Static Observation at a Safe Haven (5–8 minutes)

Purpose: See who persists when you stop.

Do: Enter a café, pharmacy, or large bookstore. Sit or stand near the window with sightlines to your entry. If driving, pull into a well-lit fuel station or large grocery lot and park where you can watch both the entrance and the lane you came from.

Watch for: A person loitering outside with line-of-sight, or a vehicle that waits without parking or parks facing your car. Note behavior, posture, and any companions.

[Leg D]

Short Loop / Rejoin (3–5 minutes)

Purpose: Re-expose yourself to the previous area from a slightly different angle.

Do: Exit and take a small loop around the block or through an adjacent aisle/side street that reconnects to your original path.

Watch for: The same subject reappearing within your line-of-sight after the loop. If on foot, glance in reflective surfaces or use your phone camera as a mirror while “reading” or “checking a message.”

[Leg E]

Brief Pause & Purposeful Delay (2–3 minutes)

Purpose: See who matches your timing.

Do: Stop to check a posted schedule, read a public notice, look at a shop window, or tie a shoelace near a corner with multiple exits. If driving, use a legal, obvious pause: pull to the curb where permitted or take a short, signed detour (e.g., posted detour around roadworks).

Watch for: The same person/vehicle adjusting to your delay rather than taking the natural flow around you.

[Leg F]

Finish at Your Safe Haven

Purpose: Make your call.

Do: Enter your chosen finish location. If you have three indicators, stay put, inform staff/security, call a trusted contact or authorities. Share your notes calmly.

An SDR is just a calm way of forcing the truth into the open.

How to Score What You Saw (Fast)

Running an SDR only matters if you can make sense of what you observed. The trick is to avoid overreacting to single coincidences while also not ignoring real patterns. A quick scoring system helps you translate scattered observations into a clear decision:
